Recalculate waveform everytime

[critictalk]

I'm using PT 10 HD. Recently I created a project and print out the mixing stems, I pressed save and quit. Every time I open this session the stems have to be recalculated. However other projects I created by this PT don't have this issue. Am I missing something?

Shot in the dark here. Where did you bounce the stems to, and what did you do with them? Just wondering if you removed them from the bounce folder(or where ever you sent them first) when you should have copied them(leaving the originals in place)

I've done an ITB Mixing and all DME were recorded in the same session and same audio file folder. After recording, I renamed DME, saved and closed the session. But when I reopened the session again, all waveform had to be recalculated.
